Triisostearin
What Triisostearin is & what it does
Triisostearin is an ester formed from glycerin and isostearic acid, making it a branched-chain triglyceride. It is used in cosmetics as an emollient and thickening or skin-conditioning agent, giving products a rich, cushiony feel. In sunscreens and other emulsions it can help disperse oils and improve spreadability; its branched structure keeps it liquid and resistant to easy crystallization.
What does Triisostearin do in skincare?
Triisostearin works as an emollient and texture-building ingredient. It is an ester of glycerin and isostearic acid, giving products a rich, cushiony feel. In sunscreens and creams it can help disperse oils and improve how the product spreads.
Is Triisostearin comedogenic?
Comedogenicity depends on the full formula and how it is used, so a single ingredient rating is not definitive. Triisostearin is a branched triglyceride ester used as an emollient, and how a product behaves on your skin can vary by individual. If you are prone to clogged pores, patch testing a finished product is a practical approach.
Is Triisostearin natural or synthetic?
Triisostearin is made by combining glycerin with isostearic acid, so it is typically a synthetically processed ester, though its raw materials can be derived from plant or other sources. The branched structure keeps it liquid and stable. The exact sourcing depends on the supplier.
